The small forehead is defined posteriorly by the indentation at blowhole. The melon merges seamlessly to the narrow,
moderate length rostrum. The mouthline is relatively straight.

Coloration

Adult males are dark gray dorsally and medium gray ventrally with pectoral fins uniformly dark gray above and below.
Scarring is often readily visible and appears to be more prevalent in adult males and can occur in round, oval or linear
patterns. Oval scars may result from cookie cutter sharks and linear lines from conspecifics given the placement of
mandibular teeth. Female pigmentation is similar to adult males, some adult females display a patch of white about
15 cm in diameter that extends from just anterior to the genital slit to a point just posterior to the anus. This
patch has not been observed in males. Juveniles have a white belly.

Size

Adult body length ranges between 4.5 to 4.9 m. Recorded maximum body length for adult males and
females is 4.8 m and 4.9, respectively. Length at birth is approximately 2.1 m.
